After finally learning that Joes son was called Wally earlier in the episode, many presumed that this new West would maybe be held off until the second half of Season 2. Wrong. With Joe and company all in the festive spirit and celebrating Christmas, a knock on the door reveals young Wally West standing there. It was certainly a WTF moment for Joe and Iris, and its also a move that throws up lots of questions. Does Wally know the whole truth about who Joe is? Why is Wally there? Has something happened to the terminally-ill Francine? Or are Joes Christmas cookery skills that impressive? Regardless, Wally West is now here. What direction the show chooses to take him is an interesting prospect. After all, in the comic books Wally is Kid Flash before eventually becoming the third man to take on the Flash mantle after Jay Garrick and Barry Allen, and hes also the nephew of Iris. Clearly hes now Iris brother, so thats one change to the character. Lets see what else the show has up its sleeve when it comes to this potential new speedster.
